CLUTCH.

original applieation filed August 9, 1910, Serial No. 576,383; Divided and this application filed April 19.

T 0 all urlio-m it may congern Be'it known that 1, CHARLES A. J UnNcs'r,

a citizen of the United States, residing at Croton Falls, in-the eountyof \Vestchester and State of New York, have invented an Improvement-in Clutches, of which the following-is a specification.

My invention relates to an improvement in clutches, a part divided out of my application for Letters Patent of the United States, filed August 9, 1910, Serial No. 576,383, for metal sawing machines, and the object ofmy invention is the provision of a strong and suitable clutch for heavy machinery for communicating motion to oppositely moving parts. In carrying out my invention and in con-' nection with a shaft of suitable character, I employ a sliding clutch member thereon and means for actuating the same.- The ends of this sliding clutch member are made as teeth adapted to engagejuxtaposed clutch teethalso upon and surrounding said shaft and forming parts of other members to be.

operated through the sliding clutch member.

A spline or key is secured longitudinally to.

saidshaft, which key also passes through the sliding clutch member. The opposing faces of the other members are recessed around the said shaft to receive collars which form the ends of a cage member surrounding the shaft and comprising with said collars a series of longitudinal rods passing through the sliding clutch and spaced circumferentially. This cage member serves the purpose of spacing the members having clutch teeth and locating the same while leaving an exact area for-the sliding clutch to move in.

In the drawing, Figure 1 is an elevation and vertical longitudinal section along the shaft and through the clutch device. Fig. 2 is an elevation and cross section at about the dotted line w; w, of Fig. 1,- and Fig. 3 is an elevation of the. cage and sliding device.

a represents pzirt of the frame of a machine and' a? a 'ousing also fdrming part of the same machine, and i represents a shaft passing through said parts. Upon this shaft a bearing sleeve i may be employed, and e represents asleeve having a sprocket e at one end and aclutch e at the other end; the teeth of the clutch being on the end and in a substantiallv vertical plane and 1911. Serial 1V0, 621,989.

the clutch within the teeth being recessed around the shaft 2'".

,k is a shaft through the housing, with a worm is thereon. meshing with a worm wheel In on the shaft 6 and one face of this worm-wheel k is provided with clutch teeth 18 surrounding the said shaft 11. and in sub:

Patented can. 9, 1912.

stantially a vertical plane and the said Worm-wheel inside of the clutch teeth-is recessed in a manner eorres'ponding'ivith the,

recess in the clutch e. There is a spline or key- Z: in the shaft 2' and around said shaft and moving upon said spline or key is a sliding clutch l having on one end teeth of similar character and adapted to engage the teeth of the clutch e, and on the other end teeth of'a similar character and adapted to engage the clutch teeth 18 so that in one po-' sit-ion of the sliding clutch Z, the teeth 18 are engaged and in the other position the teeth of the clutch e. The central portion of this sliding clutch Z is reduced to receive a roller i secured to a lever Z and thislever is connected by a pivot 19 to a lower portion ofthe housing a and I employ a cage comprising the collars 21 in the recessed portions of the clutch e and worm-wheel k", and between these collars, spaced apart, are rods 20; their reduced ends passing into said collars and the rods passing through holes in the sliding clutch Z. This cage member serves the purpose of separating the sleeve e from the hub of the worm-wheel k and keeping these parts snugly and respectively against the bearing sleeve i on the one hand and the housing a also preventing any possible crowdin or on the other hand lack of free movement longitudinally o the I screw shaft 11 of the sliding clutch member.

The lever Z with-its roller 1 is employed for moving the sliding clutch Z longitudinally of the shaft and the rods 20 so as to engage the teeth. of the adjacent members at either end thereof in order that-the shaft 1' may be rotated in opposite directions. This lever Z may be manually actuated in opposite directions, or mechanical devices may be employed for automatically actuating the sameythe clutch device being the special feature -of my present invention.

3 I claim as my invention:

tation in opposite directions. a sliding clutci:

. -10 device of the character described and in combination, a shaft adapted for romember surrounding said shaft and movable but non-revoluble thereon, clutch members adjacent to the opposite ends of the sliding clutch member provided with means for connection therewith, and a cage between said end members for spacing them apart and which cage also surrounds the aforesaid shaft and parts of which pass through the sliding clutch member.

2. In a device of the character described and in combination, a shaft,-a .clutch 1nember surroundingthe said shaft and haviiig teeth on the end faces thereof and movable but nou-revolublealong said shaft, means and rods spaced around said shaft and extending through the sliding clutch member and engaging said collars for maintaining the separated distance of the toothed elements at the opposite ends 'of thje sliding clutch. v i

3. In a device of the character described and in combination, a shaft, suitable b'earings therefor and a spline in said shaft, a sliding clutch member surrounding said shaft and means for moving-the same along said spline, said sliding clutch member hav- 5 .ing end teeth, a sleeve and integral clutch member surrounding said shaft atone end of said sliding clutch member and a member having clutch teeth also surrounding said shaft-at the other end of said sliding'clu'tch 4 member, and 'the said endclutch members within their clutch-teeth" recessed around said shaft, collars within said recesses surrounding said shaft -andsrods spaced aroundsaid shaft passing throughtlie sliding clutch 4 member and. having reduced endspassing into said collars and the collars ."and rods forming a cage for'jmaintainin the sep arated distance between the clutch members having clutch teeth at the opposite ends of 5 the sliding clutch member, substantially as setforthL I 1 Signed by me this 6th' day oflApril 1911.v
